I cut a hole big enough to slide the pcm connectors through.
But there is no grommet big enough (that I can find) to seal it up.

Did you make some kind of 2-piece cover plate to go over the hole?

Fill it with putty?

Some other solution?


(it took a pretty good size hole to get a pcm connector (and the wire bundle on top of the connector) to go through)

Maybe everybody else just pushed all the small stuff through from the inside of the car, instead of pushing the big stuff through from the engine bay side...?

I've been kicking around 2 approaches.

The first one is a plate similar to that, but with the hole in the center. And with a second plate just like it, but rotate it so the slots don't align. I'd need to put a piece of hose (probably small radiator hose) around the wires, zip-tied or hose clamped so the wire bundles become mostly round and I get a good seal. Matching the hole size to the clamped size of the hose/wire combo. The slots could be smaller than the hole, since I only have to slip one wire bundle in at a time.

The other thought is to use a piece of scrap 1/2" delrin I have laying around. Make the hole first. Then cut out a large "keystone", like from the top center of an arch. Drop the wires (wrapped in a hose) then put the keystone back on top. The keystone would have a couple of ears so I could bolt it to the top of the main piece. (it would look kind of like a stocky T with a narrow base and a wide top) The 1/2" material would support the wires better than aluminum plate.

Trying not to over-engineer it, but not wanting to set myself up for problems with the install either... I'm bringing the two main pcm bundles, the 3 smaller bundles, and the starter and alternator wires all through the same hole, between the heater opening and the passenger side cylinder head.
